RAIL-SUPPORT.

Specification of Letters Patent.

Patented July 1, 1913.

ToaZZ whom it may concern Be it known that I, WILLIAM P. DAY, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Rail-Supports, of which thefollowing is a specification.

My invention relates to railway support-s or sleepers, and is designed with special reference to the composite rail support illustrated and described in my Patent, No. 1,000,829, dated August 8, 1911, though the invention is capable of use, in certain details, with other forms of rail support.

The primary object of my invention is to provide a simple, durable and thoroughly efficient railway tie or support, having relatively few parts, and these of such character that the tie as a whole may be readily assembled, and when assembled will maximum of strength complete tie.

A further object is to so form the tie that the tie itself, can not become center-bound, a fault which is present in nearly all tie constructions, and which it is particularly desirable to eliminate.

give a and rigidity to the A further object in connection with the' above, is to provide a tie wherein a maxi mum of rigid support is given to each rail, but wherein the middle portion of the tie between the rails is made relatively yieldable, thus providing for an elasticity in the track found to be necessary for smooth running and long wear.

A still further object is to provide a tie with means which will cause the tie to have a positive engagement with the road bed, thus preventing any lateral deflection of the track as a whole under strain.

Another object is to provide a tie formed with channel and angle irons, and provide in this connection means whereby the water from the surface of the tie may be carried off and deflected from the said angle and channel irons, and to provide for proper drainage, not only for the water falling upon the face of the tie, but also provide proper drainage for the space between the ties so that the water will be carried off from the track ballast.

Another object is to provide a composite or support, and therefore the track.

tie made up of a steel skeleton frame, concrete filling and wooden pillow blocks, so arranged as to secure the greatest possible economy in the use of wood with a maximum of solidity beneath the rails, and to provide in combination with these parts rail supporting pillow blocks, easily put in place and easily removed, the parts being of standard materials, capable of being produced by any properly equipped steel mill, and without the necessity of special tools, and so constructed that the skeleton frame of the tie may be put together, either at the mill or at the track side, and that the concrete filling may be placed in position after the skeleton structure of the tie has been put in place.

Other objects and advantages will appear in the course of the following description.

y invention is illustrated in the ac companying drawings wherein: c

Figure l is an end elevation of a track support constructed in accordance with my invention. Fig. 2 is a plan view of the track structure shown in Fig. 1, the rail and rail supporting pillow blocks at one side of the structure being removed. Fig. 3 is a transverse section of a track support on the line 3-3 of Fig. 2. Fig. 4 is a transverse section and elevation of the track support shown in Fig. 2. Fig. 5 is a perspective view of one end of my improved track support. s Fig. 6 is a perspectivedetail view of the rail clamping means.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring to these drawings, it will be seen that my improved tie or sleeper comprises the spaced, parallel, transversely eX- tending beams 1, these beams being shown as [-beams, it being understood, however, that beams of any other desired cross sectional form might be used. These beams are connected in spaced relation with each other by a pair of spaced angle irons 2 and 2* at each end of the tie. These angle irons have their horizontal flanges extending in opposite directions so as to provide between each pair of angle irons a seat for pillow blocks 9, as will be lat-er described. Also arranged at opposite ends of the beams 1 are the oppositely disposed pairs of angle irons 3 and 3. These angle irons are connected to the base flanges of the beams 1 and have their vertical flanges extending downward. It is to be especially noted in this connection that the angle irons 2 are setinward of the extremities of the beams 1, and that the angle irons 3 are set at the extremities of the beams 1, and hence that there is an angular relation between the angle irons 2 and the angle irons 3, but that the inner angle irons 3 are disposed immediately below the inner angle irons 2.

The space defined by the beams 1, the angle irons 2 and 2, and the angle irons 3 and 3 is intended to be filled with concrete or other artificial stone, designated 4, and embedded in this concrete are a plurality of pillow blocks 5 which extend parallel to the beams 1 and are spaced from each other. As shown, there are three of these pillow blocks 5, two of them being arranged immediately adjacent to the inside faces of the channel irons 1, and the other being disposed midway between the first pair of blocks. It will be seen from Fig. 4 that these pillow blocks are embedded in the concrete but are less in depth than the distance between the upper faces of the channel irons 1 and the lower faces thereof, and that the blocks are spaced from each other by the intermediate concrete et These pillow blocks 5 preferably extend beneath the angle irons 2 and are preferably in contact with the under faces thereof.

It will be seen from Fig. 3, that the angle irons 8 extend down below the concrete filling 1 so that the projecting edges of the vertical flanges of the angle iron will be forced into the road-bed, and that these projecting flanges biting as they do, into the ground will positively prevent any lateral movement of the track structure as a whole. It is to be understood of course that I may use as many of these transverse angle irons 3 as desired, and I have shown one of these transverse angle irons disposed between each pair of the angle irons 3.

Yvhile the inside face of the concrete filling l beneath the illow blocks 5 is straight and vertical, as indicated at 6, the outer face of the concrete filling 1 is preferably angularly disposed as at 7, the upper edge of the concrete face being coincident with the outer edge of the angle iron 2 while the lower edge of the face is coincident with the corner of the angle iron 8. This not only directs all thrust toward the outer ends of the tie structure, but also forms a water shedding face at the ends of the tie. In order to prevent the collection of water upon the faces of the angle irons 2 and 2, and to provide for draining off any water which may fall upon the face of the tie, I fill these angle irons 2 and 2 with concrete as at 8,

'metallic skeleton of the tie,

the face of the concrete being downwardly and outwardly inclined from the upper edge of the angle iron to the lower edge thereof. This concrete filling entirely protects the angle irons 2 and 2 and serves to rapidly carry 05, not only rain water which may fall upon the surface of the track, but also carry off the brine which drips from refrigerator cars, and which is particularly destructive to metallic ties.

Resting upon the upper flanges of the beams 1 and held in place between the angle irons 2 and 2 are the upper pillow blocks 9. Preferably there are a plurality of upper pillow blocks at each end of the rail supporting structure, the concrete filling 4; extending upward between these pillow blocks 9 and the pillOW blocks 9 resting solidly upon the pillow blocks 5 below them. It will be noted that these pillow blocks do not extend laterally beneath the channel beams 1, which would render it difficult to put the blocks in place or to replace the. blocks, but that both the pillow blocks 5 and the pillow blocks 9 can be very easily inserted. The upper pillow blocks 9 are preferably covered on their lower and side faces with tar so that the space between each pillow block and the side flanges 2 and 2 and between the under side of the pillow block and the pillow block beneath is filled with tar. The upper pillow blocks 9 are held in place by means of spikes passing through the upper pillow blocks and into the lower pillow blocks 5. Preferably these spikes are screw spikes which will be later described. It will be seen that the upper pillow blocks not only afford a yielding support for the rail, but also entirely insulate the rail from the thus fitting this rail supportingstructure to be used upon roads having electrical signal systems.

The rails are preferably held to the ties by means of the screw spikes shown in Fig. 6. In this figure, 10 designates a headed spike having screw threads formed upon its shank, and 11 designates a rail clamping plate perforated for the passage of the spike and having a deflected portion 12 adapted to engage over the base of the rail. The plate 11 is formed with a prong 13 or tooth which when the screw 10 is screwed home bites into the face of the wooden pillow block 9 and locks the spike securely and prevents any rotation of the plate 12.

It will be seen that the track rails rest directly upon the upper faces of the uppermost pillow blocks and upon the concrete between these upper pillow blocks, thus affording a very solid support for the rails while providing means whereby the rails may be easily held to the tie by spikes engaging the base flange of the rail and passing through the upper pillow blocks and into the lower pillow blocks.

It has been found by actual demonstration that ties constructed as before de scribed, are particularly effective in actual use and under the severest service conditions, and that these ties are particularly valuable when disposed beneath a rail joint. In service conditions and where the heaviest rolling stock and locomotives are being used, it is found that there is no depression of the rails at the joint.

Preferably, and in order to thoroughly protect the beams 1, concrete 1% is filled in between the flanges of the channel iron. The concrete preferably extends downward as shown in Fig. 4, the face of the concrete being outwardly inclined so as to form a good drainage surface. It is to be understood, however, that the concrete 14L though it is applied on the outside and inside of the channel irons 1, does not extend beneath the middle portion. of the channel irons, but that the space designated A beneath the middle portion of each channel iron remains unfilled with either concrete or ballast so as to prevent the track from being center-bound.

It will be seen that by the construction heretofore described I have provided a tie or rail support of extreme simplicity, made up of standard materials, and of elements easily assembled, that the ends of the tie are solidly supported, while the middle portion of the tie between the rail supporting sections is free. It will, also be seen that 1 have provided means not only for protecting the metallic portions of the tie, but for carrying ofl any water which may fall thereon, and that I have also provided means projecting below the rail carrying portions of the tie and receiving the entire weight of a train passing over the track which are forced downward into the ground or road bed, and prevent any lateral movement of the track structure. Further it will be noted that by my construction I provide a concrete support for the upper pillow blocks 9 but provide for holding the upper pillow blocks 9 to the under pillow blocks 5 by means of spikes forced through the upper pillow blocks and into solid engagement with the under pillow blocks, and in this connection it may be further noted that only a minimum of wood is used in this tie, and that the wood sections are so disposed as to secure the best possible support for the rail. Further it will be seen that the uppermost pillow blocks 9 by reason of the fact that they do not extend down below and beneath the angle irons 2 and 2 may be readily removed and replaced. Another advantage of extending the concrete filling t below the under side of the channel irons 1 and thereby elevating these channel irons, is that a space is left beneath the channel irons 1 whereby drainage may take place from the ballast held between the channel irons, and, as will be seen in Fig. 4, the space between each pair of ties may be thus thoroughly drained, even where this space is filled with ballast.
